As shown in Figs. 1 and 3, the track formed by the rods and 21 is located adjacent the space between the work tables 15 and 16. Rotatable within the sleeve 27 is a shaft 29 on one end of which is rigidly secured a rotary cutting knife 30 located in the space between the work tables. The shaft-,29 also carries a pulley 31 adapted to befrotatedby a. Vrbeltzlextendins .from the pulley 33 of a motor-generator M secured to frame members 34 (Fig. 2).

The slide 24 and the rotary knife 30 are adapted tobe drawn along the rods 20 and 21 by means "of a solenoid. To this end the rods 20 and 2l support thefcasing 35 (Figs. 1, 2 and 3) of the coil (not shown) -of a solenoid. Secured to the vrbottoin'of the slide'24 by means of the stud 28 is a bent tongue 36 (Fig. 2) the free end of which '7 i's' conn'ctedto one end of the core 37 of the sole- `noid by. means kof a. link 38.' The free endl ofthe 'core7isffsupported by the coil.

The illustrated embodiment of the, present inventionisdesigned for use in connectionwith energized, a coil spring 39 is provided, one end of whichiisi clipped to the bent tongue 36l and the other end ofwhich is clipped to an ear 4'0 depending from the frame between the rods 20 and 21. The .retraction .of the slide 24 is limited by the abutment of -th'e 'slide with a split clamp 41 (Fig. 2), ,which braces the rods 20 and 21 and is secured toafframe member 42 the ends of which may be securedy to vthetop framek member 10.

For. activating the solenoid, the present invention isprovidedwitha trip 43 (Figs. 1, 3, 4 and 8) received ina'recesscut in the edge of the lower worktable V16 adjacentthe space between the two tables.v As shown in Fig. 4, the trip 43 is formed'integral with .a barY 44 one end of which is pivotedA to adepending ear 45 'secured to the bottom ofthe, lower work table 16 and the other end ofwhich isbent downwardly and formed withapassage receiving -al threaded contact 46 provided with aflocknut 47. The contact 46 normally vengagesl a contact 48 secured to but insulated from the .lower work table 16.` Viewing Fig. 4 it will be seen' that the upper surface of the trip 43 normallyrv projects a slight .distance above the. level ofthe lower work table 16, but belowvthe level: of the top of .the upper work table-.15.l To `maintain the trip 43.normally in this position, `and alsoto maintain the contacts 46 and 48v normally. engaged, the lower work table 16 is provided witha' depending stud'49 which isfreceived'by. a passage 50 in the bar 44. Threaded to the free end ofthe stud 49 is anut 51,- and a spring 52 is coiled about the stud '49.between the ,nut 51 and the bottom of the bar 44. Adjustment of the nut 51 places the spring52 under ktension to support' the trip 43 yieldingly'in its uppermost position (Fig. 4).

Thetrip and contact arrangement shown in Fig. 4iis used with'a wiring circuit provided with a 'motor and generator shown diagrammatically as Mand G,`respectively,. (Fig. 5). One terminal of the. generator G is grounded to the frame through the wire 53, while the other terminal is connected directly to the contact 48 by means ofthe wire 54. One lead wire y56 of the coil of thesolenoid S is `connectedto the wire 54. and

`coilreceives current from the4 transformerA T and `is energized, and the core 37,1 the slide 2 4, and

the knife 30are moved across the machine.

Inthe operationpf the `present invention, with a length of tacky, adhesive coated fabric 1'7 .rest.V

ing, coated sideup,uponthe upper `work `table 15 as shown in Fig.1, the operative` first places the ribbedface oran insole .18 against the fabric` 17 f so that the `fabric extends overA the i vinsole from the toe toga point-in front of the heel portion. t After pressing vthefmedian portion `ofthe insole against the fabric to,` secure a good ad?` herence, the-operative pulls the assembledfabric; and insole fromfthe upper work table l5 tothe lower work table 16 and in sodoing `causes the assembled fabric and insole to pass over the trip 43. The spring 52 is so tensionedthat any pres-,` sure thus exerted upon-the' tripj43 is not great enough to overcome the resistanceof thespring 52 and consequentlyl the trip 43 remains elevated. As the tip of the toe end of the insole `18 reaches the edge of thefupper work table 15, however, the

operativepr'esses the insole and fabric against f the lowerlwork `table lladjacentthe'vtrip 43.

thereby causing` the` fabric',` covered toe end of `the insoleyin falling off `the upperwork'table 15, to snap downagainst the trip and depress it. The

" coil of the solenoidxis thereby energized, and; as 'af result the. rotating4 knife A30 shoots along the space between the worktables 15.and 16, cutting the fabric 17,transversely and adjacent the toe Y endof` the"insole\ 18 as indicated inFig. 8. As soon as the pressure uponthe trip' 43 is released, theffsprir'ig ,39 serves "toretract the core 37,-sinc`e andthe slide` 24 and the knife 3o are retracted to their normal position." l

In-the'` operation, ofthe present invention; the

trip 43 is notl depressed to operate the` knife 3o until the tip of `thetoe end of the insole 18 falls off the upper table 15. Onthe other hand, until the knifef301severs the fabric, the fabric remains in the form ofa continuous sheet supported by bothfthe upper work table V15 and the lower work table16. ItA is therefore clearthat after the tip of the toe endfof the insole 18 leaves the upper work table 15, but before the insole is entirely withdrawn to the'lower work table 16, the toe end of the'insole will besupported by the' unl severedfabric 17 on an incline between theedge of the upper work table 15 and the"trip 43andbetween the rtrip and the lower work table 16. This being the case, the trip `43 is initially de pressed not by the tiplof the fabric coveredrib 19, but those portions .of the fabric covered rib" which lie back of its tip, that is, nearer the op- 10 thefcoilof the`-`fsolen`oid iszno longer energized,

`erative as he draws the assembled fabric `and insole through the machine. l By reason of the in'- oline of the toe endof the insole between the two work` tables, the tip `of uthe `fabric covered rib 19 is the last portion of therib to strike the trip 43. With this mode of operation, some portions of the `fabricgcovered rib .19 are ready to strike the trip 43 as soon as `the tipofthe toe end of the insole falls off the table 15 irrespective of the variationsamong different insoles of the distance betweenthe tipfof the rib 19 and the tip. ofthe toe end of the insole, or variationsamong different insoles ofnthe curvatureof the rib.` As

rib with respect'to vdifferentsizes` and/or styles of insolesado not affectthe distance the severed edge ofthe fabric projects beyond the toe end of the insole. IStated in another way, by reasonl of the manner in which` the fabriccovered toe end of the `insole 18 strikes the trip 43, the distance that the severed edge vof thefabric 17 pro- `a.`consequence, variations of theposition of the,

jects. from thetoe. end ofthe insole is always uni" form regardless of `the size and/or style of the There is no need of a gage to position the insoleproperly initiallywith respect to the path of operation of the knife, since it is not theinitial position of the ini insole assembled with the fabric.

sole ,but rather the action of the toe endof the insole that determineswhen and where the knife is to cut thefabric, and thelengthof the insole or thelength of the severed piece `of fabric has no bearing upon the actiorllof the knife.

While a given adjustmentof the trip 43 insures that the extension of.-` the fabric 17 beyond the l toe en'd oftlie'insole 18 .will be uniform for all sizes and/or" styles of insoles, insome cases it may be desirable to varythe distance the fabric extends beyond the toe `end ofthe insole. This is accomplished by varying the tension of `the spring 52, or by' changingthe adjustment of the contact 46 with relation to the bar 44 (Fig.'4)`,

or by varying vthe space t between the contacts 59 and .61!(Fig. 6).'- I

time of their assembly to the time the fabric is severed by the knife 30. If the nut 51 is adjusted to increase the tensionf the spring. 52,.it is clear that when the fabric covered toe end of the in# sole 18 snaps against the trip 43, the -increased tension ofy the spring 52 will cause the t'ripV 43 to oier a greater resistanceto the force exertedA bythe `snapping insole, and since the insole is' in motion,` the severed edge of-ftheffabric il will be spaced farther from the toel endofthe in-I sole 18 `because of the slight increase intime required to cause the .contacts 46 and '48 to disengage or the contacts 59 and 61 to engage. A

similar result may be reached by increasing the' space betweenl the contacts 59-and,61,for then the trip 43V must descend a greater distanceibefore the contacts 59 and 6l engage, and a longer; time is'th'erefore required to ybring-.the contacts 59 and 61 together, as in thecase of increasingl the ltensioncf the .spring'52. The extension of the severed edge of the fabric 1'7 from. the toe end of the insole mayV also be changed by threading the contact 4'6`farther throughthe end of the bar-44, that is, upwardly, viewing Fig. 4.v This adjustment lowers the trip 43Vand so increases the distance between the top of the work table 15 andthe trip, andconsequently a longer time is required for the fabricv covered toe end of the insole to reach the trip after falling oithe upperv Work table'15,

The illustrated embodiment'of the present invention has been described as being operatedby first assembling an insole 11S-with a continuous sheet of reinforcing fabric 17 upon the upper work tablel, and then withdrawing the assembled insole andfabric to'the lower work table 16, during `which withdrawalv the knife is automatically thrown into operation to sever the fabric. While this isl the preferred mode of operation, the illustrated embodiment of the present' invention need not be operated in this manner. It is possible Afor the operative to withdraw from the upper'work table 15 the continuous A,sheet of fabric 17 Without assembling' it with an insole,

and then, by causingthat portion of the' fabric adjacent the proposed line of severance to press against'the trip 43, the'knife`30is caused to sever the fabric. `When this lisfdone, the .operative assembles' aninsole with the severed portion ofthe fabric and'so prepares the insole for reenforcing, and this assembling neednot take place upon the lower wo-rk table 16. Itis clear that this modey of operating the machine is notV assatisfactory as `when the insole isassembled with the fabric upon the upper work table 15, since the operative must himself determine the proper position of the insole on the lfabric with respect This mode' of operation is to the severed edge. described, however, to show that vthe machine f may be utilized in more than one way.

It will be seen that .the illustrated embodiment of the present invention is simple in construction andl oper-ation. The movement. of the assembled fabric and insole is continuous and in substantially a straight line, and'is rnot interrupted as in machinesin the use of which the forward movement ofthe fabric andvinsole must, be stopped in orderto draw the fabric over the,

knife. `By coupling a manual pulling of the fabric with `an automatically moving knife, there is `eliminated all the mechanismwhich makes .ma-

chines provided with automatic feeding .mechanisms so complicated and costly. vByjreasonof .In operation ofthe present invention, the in# sole v18 and the fabric 1'7 are in motion from the theta-ipv arrangement shown the severed edge ot' the fabric is always. spaced uniformly distant from the toel end of the insoles, regardless of variations in their sizefand/or style, and this result'is achieved without the use vof the gages found necessary for this purpose'in the operation of prior art machines. Also; by operating the knife automatically, a fabric severing speed is yattained which is impossible when the knife is responsive only to the: movements of a foot treadle.

Itwill be apparent to those skilled in this art and-with the general objects of the present invention in View, that changes may be made in details of structure disclosed without departing from the true scope Vof the invention, the described and illustrated embodiment of the present invention being intended as an exploitation of the underlying essentials of the invention, the featureslwhereof are definitely stated in their true scope in the `claims herewith.
